Introduction to Tractor Hydraulic Cylinder

Tractor oil cylinder: The oil cylinder needs to be properly vented: During the installation process or when the hydraulic cylinder is parked for a long time and restarted, air will seep into the hydraulic cylinder and pipeline system. In order to prevent abnormal phenomena such as crawling, noise, and heating of the actuator, the air in the cylinder and system needs to be vented. In order to facilitate the elimination of air accumulated in the hydraulic cylinder, it is best for the oil to enter and exit from the highest point of the hydraulic cylinder. Hydraulic cylinders that require high stability in motion are often equipped with exhaust plugs at both ends. Before starting work, unscrew the exhaust plug and allow the piston to travel back and forth several times with no load throughout its full stroke, allowing air to be expelled through the exhaust plug. After clearing the air, tighten the exhaust plug before starting work. If the piston rod and cylinder are stuck or the hydraulic cylinder is blocked in the oil cylinder, no matter how it is operated, the hydraulic cylinder will not move or move very little. At this point, it is necessary to check whether the piston and piston rod seals are too tight, whether dirt and gum deposits have entered, whether the axis of the piston rod and cylinder is aligned, whether vulnerable parts and seals have failed, and whether the load carried is too high. The machining accuracy of hydraulic cylinders depends on the equipment level, production process, and testing methods. There are two commonly used methods for processing cylinder barrels, one is rough boring precision boring rolling, usually using 45 # seamless steel pipes. This method has good processing quality but high cost. Another method is to use 20 # cold drawn seamless steel pipes and then hone them, which has a lower cost. The piston rod must be tempered and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The processing of the piston must strictly follow the groove ruler and tolerance requirements given in the seal manual. When the inner surface of the oil cylinder barrel is severely worn or has deep longitudinal pull marks, it should be surveyed according to the actual object and replaced by a professional manufacturer according to the cylinder barrel manufacturing process. TS311 anti-wear repair agent can also be used to repair the cylinder barrel. TS311 anti-wear repair agent is mainly used for repairing worn and sliding metal parts. The wear of the hard chrome plating layer on the oil cylinder is mostly caused by the friction of the piston and the grinding effect of iron powder. When there is moisture in the middle, the wear is faster. Corrosion caused by the difference in contact potential of metals only occurs at the parts where the piston comes into contact, and corrosion occurs in a point like manner. Similarly to the above, the presence of moisture in the middle can promote the development of corrosion. Compared with castings, the contact potential difference of copper alloys is higher, so the corrosion degree of copper alloys is more severe.

Reference price for tractor oil cylinder

The price of tractor oil cylinders is determined by factors such as system pressure, whether pressure maintenance is required, temperature requirements, and frequency of use. The selling price varies depending on the thrust, and the cost of common tractor oil cylinders ranges from 700/yuan to 10000/yuan.

Tractor oil cylinder maintenance and related issues

• What does the maximum output force of the oil cylinder piston mean
  The maximum output of the oil cylinder is related to the pressure of the hydraulic system that links the oil cylinder to it. For example, the MOB 50 oil cylinder has a rated maximum output thrust of 1.3 tons and a rated pressure of 7 Mpa. When the input hydraulic oil pressure reaches 7 Mpa, the cylinder only outputs a maximum thrust of 1.3 tons. If the input hydraulic pressure is only 5 Mpa, the output thrust of the cylinder is only 0.98 tons. The maximum output of 1.3 tons here is because the cylinder can only withstand a pressure of 7 Mpa. If the input system hydraulic pressure exceeds 7 Mpa, the cylinder cannot withstand the pressure and will explode, causing damage. The maximum output is independent of the workload, and the magnitude of the output force depends on the hydraulic system input of the oil cylinder
• What does' dead volume 'mean in a hydraulic cylinder?
  Dead volume, also known as dead zone displacement pump, relies on the change of sealing working volume to achieve oil suction and pressure. In order to prevent the oil suction and pressure chambers from communicating with each other, there is a sealed area between the oil suction and pressure chambers. When the sealing working volume passes through the sealed area, it neither communicates with the oil pressure chamber nor with the oil suction chamber, forming a closed sealed volume Open the unloading groove, and the principle of slotting is to communicate with the oil pressure chamber when the enclosed volume decreases, and communicate with the oil suction chamber when the enclosed volume increases.
• What is the lifting capacity for a 900mm hydraulic cylinder with a pressure of 16 megapascals
  Is 900mm the stroke or cylinder diameter? You asked if there is a pulley system at the middle end, whether there is a fixed pulley or a movable pulley. Your question is invalid
• What is the cost calculation method for hydraulic cylinders?
  1. Price cost accounting: The price of hydraulic cylinders is composed of cost, profit, and tax rate. The cost includes material expenses, processing expenses, assembly and testing expenses, factory management expenses (including design and drawing expenses, management personnel salary sharing, etc.), brand promotion expenses, water and electricity expenses, equipment depreciation expenses, and other expenses. Material cost, including hydraulic cylinder barrel, piston rod, front and rear covers, guide, piston, seals, other accessories, etc. 2. Roughly estimate the price of hydraulic cylinders=weight of hydraulic cylinders * parameters, taking into account various material and processing costs. The market standard parameter is 20. The smaller the hydraulic cylinder, the lighter it is, so the parameter is enlarged. The larger the hydraulic cylinder, the heavier it is, so the parameter is reduced.
